Added an integration test for full processing of 2D complex data.  Full processing of 2D mixed mode data showed bugs in the pipe_proc.ft and pipe_proc.tp commands.  The tp bug was fixed and a unit test for it was added.  The ft bug still exists and needs to be fixed.
Reset the AQSIGN flag during ft so we don't alternate or negate twice.
Fix ft real/complex decision logic so that complex ft is still run on the direct dimension of data that require a real ft in the indirect dimension.
